Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The side plates 1 and 2, bed plate 3, engine block bar support 4, engine block support bar 5, engine block securing bar 6, engine block securing bar bolts 7, 8 and 9, grinding. Wheel 10, grinding wheel support 11, grinding wheel drive shaft 12, grinding wheel supporting bracket 13, engine block level indicator lever 14, engine block level'indicator base 15, engine block level indicator supporting bar 16, engine block level indicator supporting bar bracket 17, chain 18', sprocket 19, wheel 20, micrometer hand wheel 21, casing 22, engine head supporting base 23, head supporting bolts 24, head leveling upright 25, head leveling horizontal 26, V-8 engine block leveling bolt 27, V-8 engine block leveling bracket 28, water bafiie member 29, and water supply pipe 30, constitute the principal partsand portions of our engine cylinder block and head'gasket surface grinding apparatus.

It will be here noted that the apparatus for reciprocating the grinding wheel and maintaining the grinding Wheel in its proper relation with the bed plate is substantially the same as that disclosed and described in our former application for patent for Cylinder Block Resurfacing Machine filed May 11, 1953, Serial No. 354,049, now abandoned, and therefore no part of our present invention, and therefore only a portion is shown in the present application.

The side plates 1 and 2 and sprocket wheel, chain and hand wheel, designated 18, 19 and 20, are shown fragmentarily to disclose their relation with the rest of the apparatus. The side plates 1 and 2 are provided with sets of rollers 1a which engage a rib 1b on the base to permit reciprocation of the grinding wheel frame 13.

The bed plate 3 is provided with a straight, level upper horizontal surface throughout its whole area and is of sufiicient width and length to accommodate the longest and. widest engine cylinder blocks. Secured midway between the side edges of this bed plate are a plurality of engine block bar supports 4, which are provided with extended base portions 4a in which are mounted bolts 4b for securing said supports '4 rigidly to the bed plate 3.

These blocks 4 are provided at their upper ends with notches 4c which are adapted to receive the lower portion of the engine block supporting bar 5, all as shown best in Figures 1 and 9 of the drawing. This supporting bar 5 is beveled at its opposite sides at its upper edge leaving a narrow flat portion 5a to provide a narrow engaging portion of this bar 5 for engagement with the engine cylinder block bearings shown by dash line in Figures 1 and 9 of the drawings. This supporting bar 5 is provided in its upper edge near one end with a notch 5b which extends some distance from the upper edge thereof and positioned centrally in this notch and extending through the remainder of the member 5, is a threaded hole 50 in which is screw-threaded a bolt 5d.. This bolt 5d is provided with a head that is frusto-conical inshape. This bolt is provided for the engagement and support of engine cylinder block bearings, some of which are out of alinement with the remainder of the shaft bearings and are adjustable in the hole 5c for their proper relation for the support of such bearings, all of which is shown best in Fig. 6 of the drawing. Thus it will be noted that the engine cylinder block is pivotally mounted on this bar 5. The straight-type of engine block, as shown by dash line in Fig. 1 of the drawings, is leveled so that it is in accurate horizontalposition at its top side by means of a level indicator which includes a base which is positioned on the upper side of the block as shown bestin Figs. 1 and 2 of the drawings. Pivotally connected to one side of this base member 15 is a level indicator supporting bar 16 by means of a horizontal bar 16a, and this supporting bar 16 extends upwardly a considerable distance and is supported intermediate its ends by the supporting bar bracket 17 which is secured to the grinding wheel supporting bar bracket 13 by means of bolts 17a. This bracket 17 is provided with an enlarged portion surrounding the supporting bar. 16 and is provided with a slotted portion 17b, thus providing a clamp portion for clamping it in certain positions on the supporting bar 16 by means of a clamp screw 17c, shown best in Figures 2 and 4 of the drawings. And this bar 16 is further secured in various positions on the bracket 17 by means of a lock washer 17d. On the upper end of the bar 16 is provided an angular index member 16b; Secured to the indicator base 15 intermediate its ends is an extended hub portion 14a in which is secured the engine block level indicator lever 14 which extends upwardly at an accurate right angle to the indicator base 15, so that when the indicator. lever 14 is in alinement with the upper extended end of the level indicator 16b the upper end of the cylinder block is on a horizontal level supported on the engine block supporting bar 5, and it is adjusted and secured in this level position by means of the bolt 7a which is provided with a screw-threaded portion which is screw-threaded in the supporting portion 7 resting on the bed plate 3 and this bolt 7a is provided with a nut-like portion to facilitate its turning for adjustment of the cylinder block in a level position at its upper side. This bolt 71: is also provided with a reduced portion 7b which is arranged to fit into one of the crank case bolt holes in the cylinder block, as shown best in Fig. 1 of the drawings. .The cylinder block is further secured by means of the engine block securing bar 6, the one end of which is arranged to rest on the flange portion of the cylinder block and its other end is provided with a hub portion 6a which is secured to the bolt 9 by means of a set screw. This securing bar 6 is preferably made of spring steel so that it will yield slightly intermediate its ends when the nut 8a on the bolt 8 is turned tightly against the bar. 6, thus providing a spring-like tension against the upper side of the flange portion of the cylinder block. The bolt 8 is provided with a base portion 8b which is secured to the bed plate 3 by means of. a bolt 80 which is positioned in a slot 8d providing a longitudinal adjustment of the member 8b which provides for varying length cmgine cylinder blocks. It will be here noted that there are a plurality of these groups of engine block securing bolts 7a, 8 and 9, and their related parts, so that there may be 2 or more securing points along one side of the engine block. The bar 16d which is carried by the lower end of the supporting bar 16 is provided at its opposite ends with brackets which extend over the base 15 and are adapted to hold the base 15 substantially in alinement with the bar 16d, all-as shown best in Figs. 2 and 3 of the drawings.

In Fig. 9 is shown the apparatus for supporting the V8 type of cylinder block in level position in which the bed plate 3 is the same as is shown in the other views of the drawings and the engine block bar support 4 and engine block supporting bar 5 are the same as that shown in the other views of the drawing. However, the block is leveled by the apparatus shown in Figs. 1, 2 and 3 of the drawings for leveling the straight cylinder block, and it is supported in this leveled position by means of L-shaped brackets 28'which are secured to the engine block by bolts 28a. The other arm of the bracket 28 is provided with a hub portion 26 having a screw-threaded hole in which is screw-threaded the bolt 27, while the end of the bolt 27 is provided with a ball-bearing 27b positioned centrally in the end of the bolt with the ball bearing engaging the upper surface of the bed plate 3, and this bolt is turned by means of a head 270 which is extended for leverage purpose. It will be here noted that the V-type cylinder block may be tilted on the bar 5 so that the other portion of the cylinder block assumes a horizontal positionand the one now in horizontal position is in a vertical position and the brackets 28 and bolts 27 may be used on the vertical side in the same manner, it being noted that the cylinder head is so much out of balance that its weight holds itin secure position with the ball bearing portion 27 resting on the upper surface of the bed plate 3.

In Figs. 7 and 8 are shown the apparatus for supporting a cylinder head in proper level position for grinding the cylinder head by the same reciprocating grinder apparatus as-that disclosed in our former application for Cylinder Block Resurfacing Machine, filed May 11, 1953, Serial No. 354,049, in which case the same bed plate 3, bolts 7, 8 and 9, cylinder block bar support 4, engine block supporting bar 5, engine block securing bar 6, and grinding wheel 10 and its operating parts, are used. However, there is provided a head supporting base 23 which is longitudinally slotted at its lower side at 23a arranged to fit upon the bar 5 in snug relation therewith. This bar is adjusted and this base 23 is adjustedandsupported by means of the bolts 7, 8 and 9, and bar 6 in engagement with the lower side of the recess 23d in the one side of this base member 23 and has the same action relative to this base member as it had to the engine block as shown in Fig. l of the drawings. This base member 23 is also provided with a pair of box-like portions 23b in each of which is vertically reciprocal the head leveling upright member 25 which is provided with a plurality of notches 25a arranged to be engaged by the end of a set screw 230 which is screw-threaded into the member 23b, it being noted that there are two of these members 25 one in each end of the base member 23 and extending upwardly adjacent the opposite ends of the cylinder head shown by dash lines in Figs. 7 and 8. Secured to the upper ends of the member 25 at right angles thereto are the head leveling horizontal members 26 which extend transversely over the head of the engine cylinder head gasket engaging surface, facing upwardly, and the cylinder head is supported by means of adjusting bolts positioned in the members 24 of which there are four or more positioned at opposite corners of the cylinder head in the head supporting bolt holes, thus providing for the accurate leveling of the cylinder head relatively to the bed plate 3, and therefore relative to the grinding wheel for grinding the gasket engaging surface of the cylinder head. This cylinder head is further secured by use of bolts 23::

" which bolts are mounted in the spark plug holes in the cylinder head at theirtupper ends and in the upper portion of the member 23 at" their lower ends.

In Figs. and 11 is shown a grinding apparatus as shown in Fig. 1 of the drawings but which includes the motor in connection with its support in relation with the grinding wheel, but provision is made for cooling and cleaning the grinding surface of the grinding wheel as Well as the motor shaft and operating'parts intermediate the motor and the grinding wheel by forcing water through the shaft 12 which is the'grindiug wheel drive shaft which extends from the grinding wheel to the opposite end of the motor which shaft is hollowand water is introduced into the upper end through water pipe 12a which has one end communicating with the upper end of the hollow drive shaft 12 and connects with a water service pipe. The water is forced down through this shaft, through the motor, and down to the grinding wheel 10 where it strikes a bafile member 29, which is a circular bafiie member which forces the water from the shaft 12 outwardly between the periphery of said baffle member 29 and the inner wall of the grinding wheel 10, then under the lower surface of the grinding wheel forcing the grindings from the wheel outwardly away from the grinding wheel, all as shown by arrows in Fig. 11 of the drawings.

It will be here noted that applicants have shown and described a particular apparatus that is applicable for accurately grinding the gasket surface of straight engine cylinder blocks and V-type cylinder blocks, and also for grinding the gasket surface of engine cylinder heads, and for accurately leveling said cylinder blocks and cylinder heads, to properly and accurately position the work and this apparatus has provided means for cooling the grinding wheel as well as at the same time washing the grindings from around the grinding wheel, thus preventing overheating and surface burning the gasket surface of the engine cylinder block and cylinder head.

The operation of our engine cylinder block and head gasket surface grinding apparatus is substantially as follows: The engine cylinder block is placed in position with the bearings positioned on the bar 5 with the gasket engaging surface positioned substantialy horizontal as shown by dash lines in Figs. 1 and 9 of the drawings, and the carriage with the side plates 1 and 2, and grinding wheel supporting bracket 13 are shifted to a suitable position over the engine cylinder block and the level indicator base lowered onto the upper surface of the block by lowering the level indicator supporting bar 16. The bolt 7a is then revolved by means of the nut-like portion thereon until the level indicator lever 14 is in alinement with the indicator member 1612. Then the nut 8a is tightened onto the engine block securing bar 6 thus securing the engine block in an accurately level position for the grinding wheel. It being noted that there are two or moreof these groups of bolts 7a, 8 and 9 r along one side of the engine cylinder block on the bed plate 3. However, with the V-type block which is leveled in the same manner, it is supported by means of the blot 27 of which there may be several on the one side and when the other gasket engaging surface is to be ground the engine cylinder block is shifted so that the other face of the block is in nearly horizontal position as hereinbefore described. After the block is leveled the level indicator may be raised to a position out of the way for the operation of the grinding wheel and secured in this raised portion by the clamping bolt 17c, thus holding it in any position desired in relation to the supporting bracket 13. The grinding wheel is then lowered by means of the micrometer hand wheel 21 to a position for accurate grinding of the gasket surface of the engine cylinder block, be it either the straight type or the V-type cylinder block. When grinding the cylinder head it may be leveled and supported in the same manner by use of the bolts 7a, 8 and 9 with the securing bar 6 in engagement with the lower side of the recess 23a, in the head supporting base 23; however in Figs. 7 and 8 applicants have pr'ovided'a pair of square members consisting of members 25 and 26 which are raised and lowered near the opposite ends of the gasket surface of the cylinder head and it is secured in the same manner by means of the bolts 70, it and 9, after which the square members 25 and 2.6 are removed and the cylinder block is held by means of the bolts in members 24 which are extended into the securing holes of the cylinder head at the four corners, and the grinding wheeloperated as hereinbefore described for the cylinder block.

Though we have shown and described a particular construction, combination and arrangement of parts and portions, we do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of our invention the construction, combination and arrangement substantially as set forth in the appended claims.
